Custom labels for genome and marker lists

[donovan-h-parks]

It would be helpful if users could specify custom names/labels for the genome and marker lists they create. It is always a bit tough to remember that the bacterial marker set is id=2, the archaeal set is id=3, and the cyano set is id=7. It would be much nicer if these were 'bac', 'ar', and 'cyano'. Same for the genome lists. Ideally, the order the genome and marker sets appear would be configurable by developers. It would be fine if this required direct modification of the database.
